A # 3 brux 6mm 1-8 twist. Cerracoted black or dark gray. Going into a Mcmillian stock Black/Gray marble. Should finish out at 24". Pretty much put together from stuff I bought here on the fire. Just got the NXS 2.5 x 10 for the optics. Going to be a coyote gun for calling. I need to stay away from the classifieds!! John
